Welcome to VU.Hi. I have tried many times, try more and with less cotton, different coils, but when I close the lid it generates pressure and floods the deck. What I can do? I apologize, my desepero made me enter to forums of other countries and I am using google translator.
You might be over filling, some of the bubble tanks do better with a larger air bubble. Helps to not have the cap open for long and fill slowly if using max vg. I'd that doesn’t work you'll just have play around with the wicking.
